SYNTHESE VON 2-METHYLALANIN-PEPTIDEN, DIE pH-ABHAENGIGKEIT IHRER 13C-NMR-SPECTREN UND EINE NEUE METHODE ZUR AUSWERTUNG UEBER CS-DIAGRAMME

The uncommon amino-acid 2-methylalanine (α-aminoisobutiryc acid, Aib) was investigated by 13C-NMR.The chemical shifts of amino- or carboxy-protected derivates of Aib and of protected oligopeptides are discussed with respect to neighbouring groups and amino acids.The pH-dependence of the 13C-NMR spectra of Aib, Aib-Ala, Ala-Aib, Aib-Ala-Aib and Aib-Ala-Aib-Ala-Aib was studied.Using these examples, a new and advantageous method is demonstrated for the first time for the evaluation of NMR titration curves, which uses so-called chemical shift diagrams (CS diagrams).
